Hearts and Arrows Diamonds

Hearts and Arrow's


Born from a dream to create the world’s most brilliant diamond cut, the Hearts and Arrows diamonda feature 71 facets precisely aligned for the ultimate display of fire, brilliance and scintillation. This round brilliant cut diamond is perfectly crafted to reveal a ten hearts pattern when viewed from below and a ten arrows pattern when viewed from above through the Ideal Scope.  This diamond cut is in a class of its own and is the perfect choice for the diamond connoisseur and the perfectionist. It has the ability, not only to catch the eye, but also to capture the heart.



A diamond’s cut is the most important factor determining its brilliance. A bad cut can effect a diamond of even the highest colour and clarity grading, while an excellent cut can hugely elevate the appearance of a diamond of low colour or clarity grading. In the constant pursuit for perfection, the Brilliant 10 diamond cut was developed by Yair Shimansky and is the result of years of research into the exact science of light behaviour and optic dispersion in diamonds. The latest laser technology and state-of-the-art equipment was used to perfect this captivating diamond cut. At the hands of a Shimansky master craftsman, each of the 71 diamond facets are polished with a precise and calculated technique to realise maximum fire, brilliance and scintillation. In doing so, absolute perfection is achieved.

The Hearts abnd Arrows diamond cut takes up to three times longer to cut, and can only be polished by a handful of skilled master diamond polishers. The essence of this patented cut is its ability to reflect light: the light that enters the diamond is reflected back through the table with little to no light leakage – a world first in the diamond industry, and the Hearts and Arrows diamond’s most unique characteristic.


Tested at an international, independent diamond grading laboratory, the Shimansky signature Brilliant 10 diamond cut scored up to 25% more brilliance when compared to a round brilliant cut diamond. This means that the Hearts and Arrows diamond delivers the ultimate sparkle, increasing not only its value, but most importantly, its beauty. When looking for a diamond for an engagement ring, the Hearts and Arrows 10 diamond is the perfect choice. Its cut is as flawless as your commitment, and its beauty as deep as your love.

In a recent test, the Hearts and Arrows cut diamond was sent to a scientific and technical research centre for diamonds in Europe.

  • Light return: defined as the light returned from the diamond to the observer and accounts for light that leaves the diamond through the pavilion (base) and crown (sides). When light enters a diamond, a portion of it is returned outwards, which accounts for the stone’s sparkle. The more light returned, the better, as it means the diamond has optimum brilliance.
  • Dark Zone: the estimate of size and the negative effect of dark zones seen within a diamond.
  • Contrast: an evaluation of the number of bright and dark areas in a diamond and the variation of both.
  • Fish Eye: a reflection of the girdle on the pavilion facets visible in the face-up examination of a diamond with a very small pavilion angle.

The table below shows the calculated optical performance comparing a Round Brilliant Hearts and Arrows diamond to the Brilliant 10 diamond cut, where both diamonds weighed 1ct (one carat). The table concludes that the light return mono of the 6% higher than the Round Brilliant Hearts and Arrows diamond compared against. The light return stereo is 1% higher and the contrast is 22% higher. The dark zone mono is 14% higher.

Brilliant 10 and Eight Hearts and Arrows

Essentially, this means that the Hearts and Arrows diamond outperforms an excellent cut Round Brilliant Hearts and Arrows diamond in all measures of light return, fire and brilliance, making it the most brilliant cut diamond in the world, and the perfect diamond to express your love, or capture a meaningful moment.

In addition to the accompaniment of an independent, international certificate of authentication, the iamond is also laser-inscribed with its unique diamond identification number, and the words on its girdle in letters no larger than a few micron, and invisible to the naked eye.

Extremely rare, the diamond can only be polished from a specifically-shaped rough diamond, as the cut is dependent on the direction of the grain.

In essence, the diamond is a diamond for those who truly appreciate perfection.
